Relative detection range vs RCS
Known scenario = X
Problem scenario = Y
Detection Range Y = Detection Range X / (RCS X1/4 / RCS Y1/4)
Assume Su 30 MKI and J20 with the same radar detection rang for non stealthy jet, 170 km, assume J20 has RCS 0.001 (10 times bigger than F 22) , RCS for Su-30 MKI is 20,
then, J20 can radar can detect Su30 MKI 170 km, but Su 30 MKI can detect J20 at 170/12.28=13 km. in air battle, J20 fire PL 15 missile (range 175 km) at 170 --------------------------50 km, and shoot Su 30 MKI down, Su-30 MKI will not be able to detect J20 .
Rafale is not much better, since its RCS is 10 with 6 missiles, so then, J20 can radar can detect Rafale at170 km, but Rafale can detect J20 at 170/10=17 km. in air battle, J20 fire PL 15 missile (range 175 km) at 170 --------------------------50 km, and shoot Rafaledown, Rafale will not be able to detect J20 until 17 km,
with this, you can even make J20 RCS even bigger, as long as it is in the missile range and outside detection of Su30 MKI or Rafale, J20 will be able to shoot them down, not being detected by either of them.

India under know nothing BJP made biggest mistake for IAF should be they canceled Su57 project paid Russia $300 million for breaching contract and in the era of stealthy fighter bought Rafale none stealthy fighter with $250 million each ($88 m each for FAF) (F35 for US is only about $100 million each). If India keep working with Russia, not only India would have a stealthy fighter, but also can get a powerful AL 41 engine with max power output 173 kn, not like Rafale's tiny engine (M 88 max power out put 75 kn), so even now India wants to work with France for new engine with max power 123 kn, not even as good as Russia's AL 31 with max power out put 143 kn. we are very happy for India to make mistakes all the time. Seems there is no one , not a single one, in this country, knows what is good for India.
seems for Indians, the most important is to show off, not the real air battle.

for Indians, when they face China's stealthy jet, they just say, J20 is fake, and can be detected, by Su 30 MKI, which is totally BS, what if J20 is real stealthy?? they do not want to think about it, since the kill ratio for 5th gen fighter to 4th gen fighter could be 1:100, total Rafale India has is only 36, not only enough for 1 J20 to kill to play with. Now, as this channel reported, China has put multiple J20 in Hotian airport near Ladakh.
Unlike India, recently, US formed an "blue airforce" team with F35s to imitate China's' J20 to practice how to fight China, India is different, they just believe J20 would not work, haha :) for them what they believe MUST be true, impossible for them to be wrong, if you asked them what is your evidence? they have no concept why need evidence, their believe cannot be wrong.
